Why do red objects and text appear blurrier than other colours in low-quality digital videos?
Digital sensors use what's called a [Bayer Filter](_URL_0_) over the sensor to filter out the colours. As you can see in the images on that page, red pixels are only a quarter of the total number of pixels. This actually roughly matches the sensitivity of your eye, providing a more accurate colou…
The Short Answer
Digital sensors use what's called a [Bayer Filter](_URL_0_) over the sensor to filter out the colours. As you can see in the images on that page, red pixels are only a quarter of the total number of pixels. This actually roughly matches the sensitivity of your eye, providing a more accurate colour balance. A side effect of this is that pure red and pure blue can sometimes appear 'bitty'.
